We've now obtained the arrest affidavit in the case, and the level of violence it recounts is absolutely shocking.

The document, on view below along with plenty of new photos like the one seen here, maintains that Guzman's mom was stabbed 79 times.

Guzman's Facebook page, which remains online at this writing, features numerous stunning shots of the young woman, including this one....

...and this one....

...as well as an image of her onstage with a microphone wearing a "Hello Kitty" shirt:

These pics stand in stark contrast to the narrative of the Arapahoe County arrest affidavit in the case. The report states that Aurora police dispatch received a 911 call just past 10 p.m. on August 28 from Ryan Hoy, Guzman's stepfather.

He told the operator that Guzman and his wife, 47-year-old Yun-Mi Hoy, were inside the bathroom of the residence at 2624 South Lima Street -- and he could see blood coming under the door.

Ryan added that police had been called earlier in the day because of ongoing strife between Guzman and her mom -- and 7News reveals that the girl's father, Robert Guzman, had spoken to her about her "teen rebelliousness" about three hours before the 911 call.

"I went to talk to her because her mother was worried and wanted me to talk to Isabella," Guzman told the station. "So, I went to talk to Isabella and we sat down in the backyard looking at the trees and the animals and I started to talk to her about the respect that people should have for their parents. And I was trying to let her know that she should be obedient to her parents, not rebellious, that she should try to listen more and everything was going fine.

"In the conversation, I thought that I made progress," he added. "But obviously it didn't do nothing, because hours later, this thing happened."

Ryan was still on the phone with the 911 dispatcher as he tried to open the bathroom door, which had been locked shut. He subsequently told the operator that his wife was lying dead -- her body was near a baseball bat -- and Guzman, wearing a pink sports bra and turquoise shorts, was holding a knife.

As Guzman fled, Ryan attempted to revive his wife, but to no avail. Not only had her throat been slashed, but she'd been repeatedly stabbed. By the coroner's count, she suffered 31 stab wounds to the face and an additional 48 to her neck.

Guzman was thought to have still been in the vicinity when cops rolled up, but she managed to elude capture, at least for a while. At 11:30 a.m. the next day, as we reported, officers were called to a parking garage at 2851 South Parker Road on a report of a body inside a car. Fortunately, no body was found, but police say they located items that seemed to have links to the previous evening's violence.

Once investigators made a connection to the Guzman homicide, more cops arrived and began to canvass the area. Then, someone spotted Guzman trying to walk out of the garage. But as indicated by the photo above, taken from a nearby building, she didn't get far. She was taken into custody, and on Friday, she was formally charged with first-degree murder.

Update, 10:21 a.m. August 30: The Aurora Police Department has just announced that Isabella Guzman, eighteen, has been formally charged with murdering her mother on Wednesday night. See our previous coverage below.

Update, 5:59 a.m. August 30: Yesterday, we told you about a search for eighteen-year-old Isabella Guzman, who was described as a homicide suspect; see our original coverage below. Now, the Aurora Police Department has Guzman in custody...and we know much more about the incident in question.

The victim was reportedly Guzman's mother, who was stabbed to death -- and her daughter is said to have had a knife. Details, video and more below.

The scene of the crime.

At about 10:05 p.m. Wednesday, August 28, as we've reported, officers received a report about what was termed a "family disturbance" at a residence on the 2600 block of South Lima Street.

Upon their arrival, APD reps were met at the front door by a man who said a woman upstairs was in need of help, and that certainly proved to be the case. The adult female appeared to be in grave condition, and while emergency medical personnel were on the scene shortly thereafter, they were unable to revive her. She was pronounced dead even before she could be transported to a hospital.

Meanwhile, law enforcers released the name and photograph of Guzman, who was considered to be armed and dangerous, and launched a vigorous search that came to a head at about 11:30 a.m. yesterday, when cops were called to a parking garage at 2851 South Parker Road on a report of a body inside a car.

The parking garage.

Fortunately, no body was found, but police say they located items that seemed to have links to the previous evening's violence. And blood was indeed shed. The woman who died has yet to be officially identified, but APD spokesman Officer Frank Fania told 9News she was Guzman's mother, and she suffered multiple stab wounds, resulting in a scene described as "gruesome."

Once investigators made a connection to the Guzman homicide (no word about whether the knife with which Guzman was seen has been recovered), more cops arrived and began to canvass the area. Then, someone spotted Guzman trying to walk out of the garage. But as this photo taken from a nearby building demonstrates, she didn't get far.

Afterward, Guzman was taken to police headquarters. Thus far, however, police emphasize that they're still investigating the incident and Guzman "is not formally being held for the homicide" -- although she and her mother are said to have had a prior history of domestic strife.

Original post, 5:42 a.m. August 29: The ID photo of eighteen-year-old Isabella Guzman pictures a pretty, neatly styled young woman wearing a tasteful sleeveless top. She doesn't look even slightly out of the ordinary. She could be a friend, a sister, the daughter of friends -- or of you.

At this writing, however, Guzman is the suspect in a homicide. And her whereabouts are unknown.

Look below for more information about this tragic death and the search for Guzman.

At about 10:05 p.m. last night, according to the Aurora Police Department, officers received a report about what is termed a "family disturbance" at a residence on the 2600 block of South Lima Street.

The area is captured on the following interactive graphic; if you have problems seeing the image, click "View Larger Map."

Upon their arrival, APD reps were met at the front door by a man who said a woman upstairs was in need of help, and that certainly proved to be the case. The adult female appeared to be in grave condition, the department release notes, and while emergency medical personnel were on the scene shortly thereafter, they were unable to revive her. She was pronounced dead even before she could be transported to a hospital.

No hint about the cause of death is being shared at this point. But the police are investigating the case as a homicide.

Meanwhile, officers were told another woman, identified as Guzman, had left the house before they reached the house, and a search of the neighborhood proved fruitless.

Police call her a suspect and say she should be considered armed and dangerous.

Guzman is characterized as being five-foot six and about 130 pounds, with black hair and brown eyes. There's no description of the clothing she was wearing before hitting the road.

Anyone who sees Guzman or knows her location is encouraged to phone 911 immediately. Those with more information are also encouraged to phone Detective Mark Yacano at 303-739-6090 or Crime Stoppers at 720-913-STOP (7867), which is offering a reward of up to $2,000 in this tragic event.
